Phil Howard	4d33649cd2	HUB75: More rational DMA/PIO setup/teardown, fixes reset bug Defensively tear down DMA/PIO so it's in a known good state upon (soft)reset. Issue was a race condition with DMA interrupts firing and not being achknowledged, leaving a stuck raised IRQ. The blocking wait for DMA transactions also exacerbated this, turning a borken DMA interrupt and blank screen into an unrecoverable hardlock. ...not that the blank screen was recoverable without a soft reset anyway!	2021-11-25 17:52:44 +00:00

Phil Howard	30a455a9d5	HUB75 Less RAM, DMA flip Switch from 12-bit to 10-bit gamma to fit RGB into a uint32_t. Simplifies PIO and halves the RAM usage for F/B buffer. Switch "flip" to literally swap the front and back buffers, and then asyncronously DMA the new back buffer into the front ready for the next draw.	2021-11-24 19:31:00 +00:00
